Summary of Law and Order Seasons 1-20 DVD Box Set

At the time of its cancellation, Law & Order was the longest-running crime drama on American primetime television. Its record of 20 seasons is a tie with Gunsmoke for the longest-running live-action scripted American prime-time series with ongoing characters, although it had fewer episodes than Gunsmoke, and both series are surpassed by the animated series The Simpsons (renewed for a 26th season in September 2014).
